Question

An electric dipole is placed in an electric field increasing at the rate of $\lambda$ per unit distance along the x-axis. The dipole may undergo :

• A. rotational motion only
• B. rotational motion and translational motion along z-axis
• C. rotational motion and translational motion along x-axis
• D. only translational motion along x-axis

Answer 1

Answer: (C)

Here the electric field will produce torque and force on the dipole.
The torque will give the rotational motion and force will give the translation motion of dipole along x axis.
